Summer McIntosh breaks last supersuit-era swimming record
Canadian swimming star Summer McIntosh broke the women's 200-meter butterfly world record on Sunday night at the 2026 Canadian trials in Montreal, clocking 2:01.65. The 19-year-old beat China's Liu Zige's mark of 2:01.81 from 2009—the last remaining women's supersuit-era record—in front of a home crowd at the Olympic pool.
The swim opened Day 1 finals of the Bell Canadian Swimming Trials and instantly became the headline performance of the meet. McIntosh had entered the final as the clear favorite after topping prelims in 2:08.25, more than four seconds ahead of the rest of the field.
Key Takeaways
- McIntosh's 2:01.65 lowered Liu Zige's 2:01.81, the longest-standing individual women's swimming world record.
- It was the last women's world record still standing from the controversial supersuit era before polyurethane suits were banned in 2010.
- She shaved 0.34 seconds off her personal best of 2:01.99 from the 2025 World Championships in Singapore.
- McIntosh now owns long-course world records in four events: 200m butterfly, 400m freestyle, 200m IM, and 400m IM.
- She still has 400 IM, 400 free, and 200 IM races this week before the Pan Pacific Championships in Irvine, California.
Why was this 200m butterfly record so hard to break?
Liu Zige set the previous standard of 2:01.81 in 2009, during the supersuit era when swimmers wore hi-tech polyurethane bodysuits that dramatically buoyed times. Those suits were banned starting in 2010, but Liu's mark survived for nearly 17 years.
As the BBC reported, McIntosh's performance finally erased the last remaining women's record from that period. For a generation of swimmers raised after the ban, the 200m butterfly line on the clock had looked almost untouchable.
McIntosh herself had come close before. She went 2:01.99 at last year's World Championships—just 0.18 seconds short—and told reporters after the trials swim that she once thought this was the one record she might never break.
How did McIntosh win the race in Montreal?
According to SwimSwam's live recap, McIntosh opened in 27.45 at the 50-meter mark and turned at 100 meters in 58.21—about two tenths faster than her pace at the 2025 World Championships. She was still slightly behind Liu Zige's splits at the halfway point.
The back half told the story. McIntosh hit 150 meters in 1:29.73 and powered through a grueling final 50 as the Montreal crowd roared. Mary-Sophie Harvey finished second in 2:10.58, nearly nine seconds behind, with Claire Watson third in 2:12.58.
It was the first time many Canadian fans had seen McIntosh race at home since her move to train in Austin, Texas, under Bob Bowman, Michael Phelps's longtime coach. ESPN reported she slammed her fists into the water and smiled as the arena erupted.
What did McIntosh say after making history?
"I'm in shock right now. This means the absolute world," McIntosh said on pool deck, according to the BBC. "Growing up, this is the one world record that I thought I would never break. To do it tonight is really special in front of a home crowd."
She credited adrenaline for the closing stretch. "The last 50 was pure adrenaline," she said. "I could hear the crowd going crazy and I knew I was probably under, or close to, world record pace, so that's really what kept me going."
What comes next for McIntosh this week?
The Canadian trials continue through the week at Montreal's Parc Olympique. McIntosh is scheduled to race the 400 individual medley on Monday, the 400 freestyle on Tuesday, and the 200 individual medley on Wednesday.
Those events serve as selection races ahead of the Pan Pacific Championships in Irvine, California. For a three-time gold medalist from the 2024 Paris Olympics, the 200m butterfly may already be the signature moment of the meet—but the rest of the week could add more headlines to a trials that started with history.
